Back in 2006 the USDA created a Plum Pox Virus resistant plum through genetic engineering that they named Honeysweet. Because it was the first of it's ilk and given the nature of the US government there was a turf war over regulatory control and release of the plum was held up for a decade. Finally, in 2015, the various agencies involved signed off on releasing the plum.
According to this release statement a small amount of heat-treated budwood was available through the Clean Plant Center Northwest, which is at the University of Washington, and the official repository of budwood was to be the National Plant Germplasm System of which UCDavis is responsible for plums.
I checked both places and Honeysweet is not listed as being available at either one.
Has anyone heard of Honeysweet plums and where to get a plant or budwood of it? I want it for breeding of the PPV resistance gene which, as it happens, also confers immunity to Black Knot.
